can you control how lean/rich your car runs with MHD?

i know COBB runs rich.

Excellent. Thanks for the lesson!

we can control everything we need to control to give the best possible tunes on these cars with MHD. So you have nothing to worry about. We control pretty much all parameters necessary

I ditched Cobb as soon as MHD was available for N55. I’m much happier now and the car is running very well.

when your customer logs, what are you having them do?

For the logs i generally ask for the following (unless im looking for something else specific):

****DSC Completely turned off for all logging****

1. normal driving acceleration from a dead stop up to cruising speed and cuise for like 20-30 seconds.
2. 3rd and a 4th gear WOT pull from 2800-3000rpms start point up to about 6500rpms
3. a third gear shifting into 4th gear WOT pull. starting in 3rd gear around 3500rpms or so. once in 4th hold WOT for about 3-4 seconds and let off. (this checks post shift timing recovery).

Please include the following parameters in yours logs:

Accel Ped. Pos.
Berechnetes Ist-Moment in der Funktionsüberwachung
Boost
Boost target
Boost Target Ex
Fuel mode
Gear
IAT
Lambda bank 1
LTFT
MAF
Oil temp
Rail pressure mean
RPM
STFT 1
Throttle Position
Timing Cyl. 1
Torque act. clutch
WGDC
Boost setpoint factor
Cyl1 Timing Cor
Cyl2 Timing Cor
Cyl3 Timing Cor
Cyl4 Timing Cor
Cyl5 Timing Cor
Cyl6 Timing Cor
Load actual
Load req
MAF req. WGDC
WGDC After PID
WGDC base
WGDC Spool


Yes i ask for 4th gear pulls, but are at the owners discretion. Why? 4th gear gives the most data and most accurate viewpoint of what boost is doing. There are a few other reasons as well. But i understand some people dont like doing 4th gear pulls because of the speed logged at that gear. In that even 3rd gear would suffice.

Going through a custom tune with justin now. Couldn't be happier with the process and service. Would highly recommend going custom mhd with justin over the now defunct Cobb
